It was built in 1925-26 to designs by the New York firm Sugarman and Berger.","why_significant":"The nomination argues the building is one of the city's most original apartment houses, an early merger of tall apartment construction, suburban garden setting and automobile access. Its Regency and Adam-inspired interiors are described as among the finest of their period, and its design is said to have been carefully tailored to the traditional values of prospective tenants.","narrative":"Built in 1925-26 on a corner of Lincoln Drive in Philadelphia by the New York firm Sugarman and Berger, the fourteen-story apartment house is set back from the road, with its Lincoln Drive front left open as a lawn and terraces near the headwaters of the Wissahickon Creek. Its facades use a stone base, two stories of Corinthian pilasters, and brick upper floors with Regency-style windows, topped by a double attic story and a corner tower. The lobby features Ionic piers, a coffered ceiling, and a black and white marble floor, and the cocktail lounge and dining room are equally elaborate. The building holds 244 apartments, and it is significant as one of the first apartment houses in the region to combine tall construction, a suburban setting, and a garage for automobiles. Its traditional styling was chosen to appeal to conservative local tastes, and the design is regarded as an early example of this approach.","period_of_significance":"1925-26","architect_builder":"Sugarman and Berger (architects)","architectural_style":"Regency","criteria":["C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.056014-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/82003811.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82003811/7269aae3ac-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82003811/7269aae3ac-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lot_at_401_W_Johnson_Philly.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Lot_at_401_W_Johnson_Philly.JPG"},"district":{"nrhp_refnum":"72001151","name":"Fairmount Park","url":"https://nationalhistoricalregister.com/districts/pennsylvania/fairmount-park-72001151/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997054","wikipedia":"https://en.wikipedia.org/wiki/Mayfair_House","wikidata":"https://www.wikidata.org/wiki/Q6797126"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/mayfair-house-82003811/"}
